Five Star LC Epoxy Grout

Five Star LC Epoxy Grout

Five Star LC Epoxy Grout is a highly flowable, non-shrink, rapid strength gain, epoxy grout for tight clearance applications and dynamic loads. This versatile product is formulated for placement into low clearance applications as thin as 3/8 inches (10 mm) in depth dependent on specific placement requirements while achieving very high mechanical properties.

  • High Flow for Tight Clearances
  • Excellent Adhesion to Steel
  • Rapid Strength Gain

SKU: 17642

Five Star LC Epoxy Grout is a precision-engineered, high-performance grout designed for structural applications that demand reliable support in tight clearance conditions. This three-component, 100% solids epoxy system is formulated for installations where flowability, strength, and chemical resistance are essential. With the ability to be placed at depths as low as ⅜ inch (10 mm), it provides a practical solution for industrial settings where space constraints and load-bearing requirements intersect.

Engineered to withstand dynamic and cyclical loads, Five Star LC Epoxy Grout offers rapid strength development — reaching compressive strengths of 13,000 psi within 24 hours — enabling faster equipment commissioning and reduced downtime. Its expansive, non-shrink formulation ensures full contact under baseplates and machine frames, delivering consistent load transfer and long-term stability.

The high flow characteristics make it especially effective in applications involving crane rail systems, transfer car runways, light rail installations, and other heavy-duty equipment foundations where traditional cementitious grouts may fall short. In addition to its mechanical properties, the grout offers strong resistance to chemical attack, making it suitable for use in harsh industrial environments including chemical plants, material handling facilities, and manufacturing floors exposed to solvents or oils.

Whether grouting under tight tolerances or supporting equipment subject to vibration and thermal cycling, Five Star LC Epoxy Grout delivers consistent results backed by tested performance and field-proven reliability.

Recommended Uses

Five Star LC Epoxy Grout is formulated for installations that require high compressive strength, excellent chemical resistance, and dependable placement in limited-clearance conditions. Its performance in heavy-duty industrial environments makes it a strong choice for projects where structural durability and precision matter.

Typical applications include crane rail and light rail baseplates, transfer car and material handling tracks, and precision equipment installations with tight anchor tolerances. It is also used in railroad track rehabilitation and industrial equipment foundations subject to vibration or torque. This grout is particularly effective in high-precision environments where consistent flow, strong bond development, and rapid strength gain are critical to long-term performance.
